Wow this looks very cool!

Silly question you mention lithium battery technology, I assume currently they're not re-chargeable lithium? But could you possibly make the label re-chargeable with a coil + lithium ion chemistry?

Thanks. Correct, it’s not rechargeable. Rather, primary (non-re-chargeable) lithium-based electrochemistry in very tiny amounts on thin films. We do have some energy harvesting stuff up our sleeves here too, but that’s down the road a bit.
